FURNACE.

Application led April 16, 1926. Serial No. 102,376.

d furnish a heating chamber with communi cating air chambers in whichcold air may be expeditiously and economically heated and supplied tooil burners constituting the main source of heat for the heatingchamber.

The above and other objects are attained by a furnace construction thatwill be hereinafter specifically described and'` then claimed, andreference will now be had` to `the drawing wherein Figure 1 is a rearelevation of the furnace;

Fig. 2 is a horizontal sectional view of the same, and

Fig. 3 is a vertical longitudinal sectional View of the furnace taken onthe line III- III Fig.'1. y

In the drawings, the reference numeral 1 denotes a heating chamberwithin an inclosure that may include a bottom wall 2, a front wall 3, arear wall 4, side walls 5, and a top wall 6 havingan exhaust stack orflue 7 The front wall 3 has a bottom doorway 8 with an air supply pipe 9adapted to direct a blast of air through the doorway 8 into the heatingchamber 1 to sustain combustion therein and prevent'the escape of heatedair at the doorway 8,

The rear Wall of the furnace has two spaced apart openings 10,preferably in a common horizontal plane, connnunicating with air heatingchambers 11 mounted against the rear wall 4 ofthe furnace.

Extending downwardly between the air chambers 11 is a cold air supply orinlet pipe 12 provided with a conventional form of valve or gate 13 thatmay beL adjusted from either side of the furnace by a. valve controlmechanism 14. The lower end of the cold air supply pipe 12 has lateralblanches `15 provided with nozzlesv16 extending into openings 17 in theconfronting inner walls of the air heating chambers 11. The nozzles 16supplyblastsof air to the air heating chambers 11 andthe blasts of airare directed transversely or. across the air heatlet pipes 18 whichextend along the sidev walls 5 of the furnace communicating with opposedoilburners 19 having nozzles 20" protruding through openings 21 in theside walls 5. The oil burners 19are of a conventional fornrsupplied byoil pipes 2Q and said burners have suitable control valves or regulatingmechanism 23. Y

The heated air from the chambers 11 to the oil burners insuresatomization of oil and a proper admixture to sustain a perfectcombustion within the heating chamber 1. Obviously the air heatingchambers Vmay be attached to various types of furnaces and for thisreason I do not care to confine my invention to the preciseconstruct-ion and ar" rangement of parts shown, other than defined inthe appended claims. 1

Vilhat I claim is :e

l 1. A furnace of the class described comprising a heating chamber, oilburnersfor heating said chamber, air heating chambers communicating withsaid heating chamber, hot air outlet pipes communicating with said airheating chambers and said burners to supply air thereto, and cold airinletl pipes communicating with said air heating chambers to supply airthereto, the cold air inlet pipes having their outlets aligned with andspaced from the inlets of the hot air outlet pipes so that the supply ofcold air traverses said air heating chambers.

2. A furnace as called for in `claim Al,v wherein said oil burners areat the sides of said furnace in opposed relation, and'said air heatingrchamber at the rear side of said furnace with said hot air outlet pipeseX-` tending forwardly at the sides of said furnace.

3. Means for supplying heated air toja furnace for combustion purposestherein, coi'nprising air heating chambers ceinnnini` cat-ing with thefurnace, hot air outlet pipes having open ends in said air heatingcha-mbers, and cold air inlet pipes communicaty ing with said air'.heating chambers and adapted to discharge a blast of cold air intoV eachair heating chamber in the direction of the hot air outlet pipes.v

In testimony whereof I affix my signature.
